This equipment uses a high-definition CCD camera to scan the surface of the display screen, collect images and process them to identify and classify defects on the product.

[0003] The working principle of AOI inspection equipment is based on the automatic scanning function of high-definition CCD cameras. When the equipment is running, the camera scans the surface of the display screen and analyzes the captured image through pattern recognition. This technology can effectively identify tiny defects on the product, including scratches, cracks, solder joint problems, etc. The equipment will also compare the detected image with the qualified parameters in the database. After image processing, the defects on the target product are checked and displayed through the display or automatic marking. ‌
